South Korea’s Samsung Electronics Co Ltd has introduced a range of LED components for use in advanced mobile devices such as smartphones and tablets.
The LEDs include two reflector-integrated flash LED packages - the 3432 1.8t (FH341A) and 3432 1.4t (FH341B), plus a flip-chip flash LED 2016 (FH201A), as well as two side-view LEDs - the 3810 0.6t (MS062F) and 3810 0.8t (MS082F).
The new LEDs are being showcased in hall 2, booth 2G40 at the Mobile World Congress 2014 at Fira Gran Via, Barcelona, Spain (24-27 February). Samsung will start mass producing the new mobile-market LEDs in March, which are likely to then begin appearing in the open market in second-quarter 2014.
Reflector-integrated flash LED for high-end mobile devices
Because high-quality smartphone cameras require a wider FOV (field of view) angle for better picture quality, Samsung’s new reflector-integrated flash LEDs are designed to enable great flexibility by providing a wide FOV within a small space through the integration of a light source, a lead frame, and a reflector with its own optics and diffusion features.
Of the latest LED mobile offerings, Samsung’s new reflector-integrated flash LED - the 3432 1.8t (FH341A) delivers over 165 lux at 1A and a minimum CRI (color rendering index) of 80. The 3432 1.8t is being used in the next Galaxy smartphone, for introduction in February.
Also new to the reflector-integrated flash LED line-up is the 3432 1.4t (FH341B), which is designed specifically for mobile OEMs seeking extra-slim LED solutions. The 3432 1.4t package includes a reflector and is only 1.4mm thick, suiting smartphones and tablets thinner than 7mm. In addition, it provides minimum illuminance of 165 lux.
Standard flash LED with high light quality
The new standard flash LED 2016 (FH201A) applies Samsung’s proprietary cell-film phosphor technology to flip-chip packages, which applies a thin film of phosphor to each package. Providing design flexibility, Samsung’s first 2016-sized flash LED package offers 220lm output and improves color deviation by about 40% compared with packages using Samsung’s previous technology that dispensed phosphor onto each chip. This more affordable LED solution also offers a high level of color quality (rare to traditional flash LED products).
High-brightness side-view LEDs
The 3810 0.6t (MS062F) and 3810 0.8t (MS082F) side-view LEDs feature high color reproducibility, due to their high brightness levels. Their packages are also power-efficient, operating on less than 2.9V.
The 3810 0.6t provides 3.1cd, while having a z-height of just 0.6mm, suiting slim smartphones and tablets. The 3810 0.8t offers more luminous intensity (3.2cd), with a 0.8mm thickness, making it suitable for tablet and notebook PCs.
